Decoder Mode

The decoder mode is selected by connecting “MODE” pin

to vss.

The decoder receives the serial data from the detect circuit and outputs the comparison result or data, if it is valid. The received data may inolude two types

-

without data and with data.

For decoder without data

For decoder with data IC, such as UM375&106A/B and

examined bit by bi as received. The first 10 bits

(ex. UM375&106A/B) are assumed to be address bi. If the address bits
